Computer Technology a challenge

It is a beautiful summer day here in the Northwest. Retired and keeping busier than ever expected, I sit trying to understand he technology tied to uploading photos to different web sites that I am involved in. What a frustration. Keeping track of passwords and instructions is overwhelming. That said, I count my blessings to be alive and having the freedom to even have this problem. It is my goal to see how in the world I handle this and learn how to deal with this. I would like to learn this once and for all and then come back and forth becoming active in my blog. My goal is to find a human body to come to my home and work with me. If I can do that I will be assured of learning how to move around and enjoy my blog and my classes. Website instructions given, which apparently are excellent for some, hasn't worked for me.
